  6. /**
  7. * Allows modules to define their own translation info.
  8. *
  9. * Entity Translation relies on the core entity information to provide its
  10. * translation features. See the documentation of hook_entity_info() in the core
  11. * API documentation (system.api.php) for more details on all the entity info
  12. * keys that may be defined.
  13. *
  14. * To make Entity Translation automatically support an entity type some keys
  15. * may need to be defined, but none of them is required except the 'base path'
  16. * key if the entity path is different from ENTITY_TYPE/%ENTITY_TYPE (e.g.
  17. * taxonomy/term/1). The 'base path' key is used to determine the view, edit and
  18. * translate path if they follow the default path patterns and to reliably
  19. * alter menu information to provide the translation UI. If the entity path
  20. * matches the default pattern above, and there is no need for a dedicated
  21. * translation handler class, Entity Translation will provide built-in support
  22. * for the entity.
  23. *
  24. * The entity translation info is an associative array that has to match the
  25. * following structure. Three nested sub-arrays keyed respectively by entity
  26. * type, the 'translation' key and the 'entity_translation' key: the second one
  27. * is the key defined by the core entity system while the third one registers
  28. * Entity translation as a field translation handler. Elements:
  29. * - class: The name of the translation handler class, which is used to handle
  30. * the translation process. Defaults to 'EntityTranslationDefaultHandler'.
  31. * - base path: The base menu router path to which attach the administration
  32. * user interface. Defaults to ENTITY_TYPE/%ENTITY_TYPE.
  33. * - access callback: The access callback for the translation pages. Defaults to
  34. * 'entity_translation_tab_access'.
  35. * - access arguments: The access arguments for the translation pages. Defaults
  36. * to "array($entity_type, $entity_position)".
  37. * - view path: The menu router path to be used to view the entity. Defaults to
  38. * the base path.
  39. * - edit path: The menu router path to be used to edit the entity. Defaults to
  40. * "$base_path/edit".
  41. * - translate path: The menu router path to be used for attaching the
  42. * translation UI. Defaults to "$base_path/translate".
  43. * - path wildcard: The menu router path wildcard identifying the entity.
  44. * Defaults to %ENTITY_TYPE.
  45. * - admin theme: Whether the translation UI should use the administration
  46. * theme. Defaults to TRUE.
  47. * - path schemes: An array of menu router path schemes used for attaching the
  48. * entity translation UI. This element can be used to declare additional path
  49. * schemes, if an entity type uses multiple schemes for managing entities
  50. * (e.g. different schemes for different bundles). Each path scheme can define
  51. * the following elements (descriptions see above): 'base path', 'view path',
  52. * 'edit path', 'translate path', 'path wildcard' and 'admin theme'. All path
  53. * elements that are defined directly on the entity translation info array are
  54. * automatically added as a 'default' path scheme.
  55. * - theme callback: The callback to be used to determine the translation
  56. * theme. Defaults to 'variable_get'.
  57. * - theme arguments: The arguments to be used to determine the translation
  58. * theme. Defaults to "array('admin_theme')".
  59. * - edit form: The key to be used to retrieve the entity object from the form
  60. * state array. An empty value prevents Entity translation from performing
  61. * alterations to the entity form. Defaults to ENTITY_TYPE.
  62. * - skip original values access: A flag specifying whether skipping access
  63. * control when editing original values for this entity. Defaults to FALSE.
  64. * - bundle callback: A callback to check whether the passed bundle has entity
  65. * translation enabled. If empty all bundles are supposed to be enabled.
  66. * - default settings: The defaults to be applied to settings when an explicit
  67. * choice is missing.
